Sage (Salvia officinalis) — identification, habitat & look-alikes

Common sage is the gray-green, fuzzy-leaved herb behind classic poultry stuffing. It's a Mediterranean native that grows as a small evergreen shrub, and in early summer it sends up spikes of lavender-blue flowers that bees and butterflies love. It's also called garden sage or culinary sage.

Appearance

Growth form: An evergreen with woody lower stems, usually about 1–2 ft (30–60 cm) tall and 2–3 ft (60–90 cm) wide.
Leaves: Opposite, oblong, gray-green leaves with a pebbly, wrinkled surface; the undersides are almost white with soft hairs. They are strongly fragrant.
Flowers: Two-lipped flowers on upright spikes, usually lavender-blue, sometimes white, pink, or purple. Blooms in late spring to early summer.

Look-alikes

White sageSalvia apiana

White sage has paler, almost whitish leaves and is a bigger shrub, about 4–5 ft (1.3–1.5 m) tall, with white to pale lavender flowers on stalks rising 3–4 ft (1–1.3 m) above the leaves. It grows wild only in Southern California and Baja California.

Why they get mixed upBoth are fragrant, hairy-leaved sages, and dried white sage is widely sold as "sage."

Big sagebrushArtemisia tridentata

Sagebrush leaves are small, wedge-shaped, and split into three lobes at the tip, and it has tiny yellow flowers in late summer or fall. It is a daisy-family shrub of the dry Intermountain West, not a true sage.

Why they get mixed upIt's called "sage" across the West and has silvery, strongly scented leaves.

Where it lives

Typical habitats: Herb gardens
Sunny, dry ground
Range: Native to the northern Mediterranean (Spain, France, Italy, Greece, the Balkans). In the US it is mostly a garden herb, though it is listed as introduced in parts of the country.
Preferred conditions: Needs full sun and well-drained soil. Drought tolerant, but cold, wet winters and soggy soil often kill it. Hardy in USDA zones 4–8.

Growing it

Propagation: Easy to root from summer cuttings; some varieties are grown from seed.
Toxicity: The leaf oil contains , which can be harmful in large doses. Normal cooking amounts are a different matter from concentrated oils or supplements.

Name and classification

About the name: Spanish sage is treated as a subspecies of common sage in some classifications and as its own species (Salvia lavandulifolia) in others.
Varieties and forms: Popular garden varieties include gold-variegated 'Icterina', purple-tinged 'Purpurascens', and green, white, and pink 'Tricolor'. The purple and tricolor types are not winter hardy.

Culture and stories

Culture and stories: Sage shows up in sage-and-onion stuffing, Italian saltimbocca, and England's green-marbled Sage Derby cheese.

Ancient Greek and Roman physicians wrote about it, and Charlemagne recommended growing it in the early Middle Ages.
